Thanks to @BasMilius fantastic Apple TV app I built this Flow to play a fireplace movie. Started from a virtual switch exposed to Apple Home for voice activation, it plays the movies intro music before then passing over to a randomised classical music playlist from Apple Music played on a Sonos Beam in the living room. It uses a Chronograph timer to then scrub back to the beginning at the end of the movie but continuing the music without the movie intro music. Moving back out of the movie and playing something else or turning off the TV ensures the music stops.
Creating a perfect Sunday afternoon reading.
Then in the evening, when I turn off the TV in the living room it starts the same fireplace loop on the bedroom TV, this time without the music.
A button next to the bed turns off the TV and starts the night time lock down flow. Plus there’s another button to start the fireplace loop anytime of day, for lazy Sunday mornings.
